Abstract: Unmanned aerial vehicle (UAV) aeromagnetic survey is gradually applied to the field of small and medium-sized large-scale resource exploration due to its advantages of high efficiency, safety, and low cost. This study aims at the structure description and prospect prediction of the 22 km2 area in Sanshan district, Wuhu City, Anhui Province. For this purpose,the 1:20 000 high-precision UAV aeromagnetic survey was carrued out. The authors deduced the process of Euler inversion, analyzed and compared the selections of the tectonic index, used Euler deconvolution with the tectonic index 0 to solve the aeromagnetic data inversion, and finally obtained the structural boundary solution set information of the underground magnetic anomaly body. This was applied to the inversion of aeromagnetic data in the study area. According to the boundary position and depth information obtained from the inversion, 18 faults are recognized and combined. A magma distribution area of 8.7 km2 is delineated based on the anomalous characteristics. According to the metallogenic characteristics of an iron ore in Ningwu area, the magmatic distribution area and its boundary are determined as a detailed metallogenic survey area.

Key words: UAV aeromagnetic measurement, Euler deconvolution method, tectonic interpretation
